What is Negative Pressure?

The condition established by the collection equipment during a proper cleaning, so that everything dislodged is drawn out rather than redistributed. It is what separates source removal from moving contamination around, and it is the reason a legitimate cleaning requires access openings and equipment rather than a shop vacuum.
